I believe it is necessary to get baptized to go to heaven. Getting baptized leaves a permanent mark on your soul, it is sanctifying grace. Sanctifying grace is where God imprints a part of himself into you. This grace is a free undeserved gift that God gives you upon things like baptism and confirmation. Thus giving you the holy spirit and the ability to go to heaven.
You half right xgamer. It is not like light coming out of the water, but it is not just some ordinary drinking water. The holy water is blessed, but not in a way that light comes out of it. Do you kinda get it?
So, in order for it to be holy it must be physically changed?
Let me ask you something DonkeyKong13
When you were confirmed, im saying confirmed because i doubt you remember your baptism, were you physically changed? i think not... But, im sure you felt a mental/spiritual change.
